5D3 + AI-Servo + Airplanes

Decided to see how well AI-Servo works on my 5D3. So I went out to the airport and shot serveral series of planes on approach with my 70-200 f/4L IS. My settings were AI-Servo, single point expanded, case 2. My hit rate was at least 90%. Very pleased.

This series of three shots is pretty representative of what I was getting.
